Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, and more particularly to a cage frame with adjustable length. Background Art

[0002] In filtering equipment, using storage filter bags for storage filtration is a common way of gas dust removal. During operation, the inflowing air is filtered through the filter bags, so that the clean air passes through the filter bags into another part of the equipment. During this period, in order to ensure that the filter bags can remain stable when subjected to gas impact, cage frames will be set on the inside of the filter bags for support to ensure the structural stability of the filter bags.

[0003] Common cage frames are mostly simple and fixed. Their size is fixed during use and can only support filter bags of a certain size. However, there will always be certain errors in production, resulting in a mismatch between the filter bag and the cage frame, resulting in problems such as the filter bag being too long or too short. If it is too short, it cannot be used. If it is too long, it will affect the support effect of the filter bag, causing the filter bag to twist and deform when impacted by airflow, affecting the dust removal effect. Moreover, the cage frames of fixed structures are mostly one-piece structures, fixed together and cannot be disassembled. When part of the cage frame is subjected to excessive impact and breaks, the entire cage frame needs to be replaced and the original cage frame is discarded, resulting in material waste. In addition, most common cage frames are simple in structure, only have a supporting effect, and have a single function and limited effectiveness. In actual operation, in order to increase the working time of the filter bag, a backflush system is used to blow air in the opposite direction to blow dust off the surface of the filter bag, thereby cleaning the filter bag surface. However, because the cage frame supports part of the inner part of the filter bag, the airflow cannot effectively pass through the corresponding part of the filter bag, making it difficult to clean the dust on the filter bag surface corresponding to the cage frame.

[0035] Specifically, when the frame 1 is installed to support the filter bag, the air supply pipe 15 at the outer end is connected to the external gas supply equipment. During operation, steam for cleaning is introduced into the air supply pipe 15, and the steam flows into the integrated frame 12 along the air supply pipe 15, and then flows into the multiple vertical frames 9 from the insertion hole 13, circulates along the ventilation cavity 14, and then flows out from the multiple first air outlets 16 to clean the filter bag closely attached.

[0039] Specifically, through the cooperation of the air supply pipe 15 and the connecting hose 21, the integrated frame 12 between the upper frame 2 and the lower frame 3 is connected, so that the steam in the ventilation cavity 14 can flow into the integrated frame 12 and then flow into the other integrated frame 12 through the connecting hose 21, thereby allowing the steam in the upper frame 2 and the lower frame 3 to interact and ensure uniform steam inflow.

[0040] Please refer to Figure 2-Figure 4 As a further embodiment of the frame: a reinforcing rod 22 is provided on the integrated frame 12 at the lower end of the upper frame 2, and a sliding plate 23 is provided on the integrated frame 12 at the upper end of the lower frame 3, and the reinforcing rod 22 and the sliding plate 23 are slidably matched.

[0041] Specifically, when combining the upper frame 2 and the lower frame 3, the reinforcing rod 22 is inserted into the sliding plate 23 so that the reinforcing rod 22 passes through the integrated frame 12, and the reinforcing rod 22 is staggered with the vertical frame. When adjusting the position of the upper frame 2 and the lower frame 3, the reinforcing rod 22 slides along the integrated frame 12 to adapt to the change in length.

The fixing plate 26 is detachably matched with the fixing hole 25 through fixing bolts.

[0045] Specifically, after completing the combination of the integration frames 12 at both ends and the vertical frames 9, the fixing plate 26 is placed on the inner side of the integration frame 12, and the fixing bolts are matched with the fixing holes 25 to provide an effect, and the fixing plate 26 is fixed to the inner side of the integration frame 12. The two ends of the fixing plate 26 are respectively connected to different integration frames 12, thereby ensuring the stability of the position of the integration frame 12, making the integration frame 12 stably matched with the vertical frame 9, and ensuring the structural stability of the frame body 1.

[0046] To sum up, when the overall device is in use or running:

[0047] When the equipment is used, the frame body 1 is assembled, and the corresponding number of vertical frames 9 and cross frames 10 are prepared. The frame body 1 is assembled, and the cross frames 10 are installed at an appropriate distance and placed vertically. Then, the vertical frames 9 are placed around the cross frames 10, so that the inner sides of the vertical frames 9 limit the cross frames 10 through the support plates 11, and limit the longitudinal movement of the cross frames 10. The horizontal movement of the cross frames 10 is limited by the cooperation of multiple vertical frames 9, thereby fixing the position of the cross frames 10. When the cross frames 10 are matched with the vertical frames 9, the vertical frames 9 will sink into the inner groove 24, so that the connecting pipe 20 is inserted into the connecting port 19, so that the outer ends of the cross frames 10 and the vertical frames 9 are on the same arc surface, so that the cross frames 10 provide effective support for the filter bags while ensuring the structure of the vertical frames 9. Then, the integrated frame 12 is installed to the upper and lower ends of the vertical frames 9, so that the ends of the vertical frames 9 enter the insertion holes 13, thereby 2 Fix the position of the vertical frame 9. After completing the combination of the integrated frames 12 at both ends and the vertical frames 9, place the fixing plate 26 on the inner side of the integrated frame 12, and provide an effect by cooperating with the fixing bolts and the fixing holes 25 to fix the fixing plate 26 to the inner side of the integrated frame 12. The two ends of the fixing plate 26 are respectively connected to different integrated frames 12, thereby ensuring the stability of the position of the integrated frame 12, making the integrated frame 12 stably cooperate with the vertical frame 9, and ensuring the structural stability of the frame body 1. According to the above method, the upper frame 2 and the lower frame 3 are assembled, and the reinforcing rod 22 is inserted into the sliding plate 23 so that the reinforcing rod 22 passes through the integrated frame 12, and then the threaded rod 5 is cooperated with the extension frame 6 to make the upper frame 2 and the lower frame 3 cooperate, and fixed by the fixing nut 8 to form a complete frame body 1. In addition, by performing the above steps in reverse, the frame body 1 can be disassembled and part of the structure of the frame body 1 can be replaced.

[0048] When the equipment is working, the filter bag is supported by the frame 1, and the position of the upper frame 2 and the lower frame 3 can be adjusted according to the size of the filter bag. The fixing nut 8 on the threaded rod 5 is loosened to leave enough space between the fixing nut 8 and the extension frame 6, and then the upper frame 2 is moved so that the upper frame 2 pulls the threaded rod 5 to move through the extension frame 4. The threaded rod 5 moves along the sliding hole 7, thereby changing the relative position of the upper frame 2 and the lower frame 3. When adjusting the position of the upper frame 2 and the lower frame 3, the reinforcing rod 22 will slide along the integrated frame 12 to adapt to the change in length. During work, the reinforcing rod 22 The rod 22 can provide support strength in the horizontal direction, resist the impact of airflow from the side end, and ensure the overall stability of the frame 1. After the adjustment of the length of the frame 1 is completed and the appropriate length is reached, the fixing nuts 8 at both ends are tightened so that the fixing nuts 8 clamp the extension frame 6, thereby fixing the threaded rod 5 and keeping the positions of the upper frame 2 and the lower frame 3 fixed. In addition, when the frame 1 is installed to support the filter bag, the air supply pipe 15 at the outer end is connected to the external gas supply equipment. During operation, steam for cleaning is introduced into the air supply pipe 15, which can flow into the integrated frame along the air supply pipe 15. 12, then flows into the multiple vertical frames 9 from the insertion hole 13, circulates along the ventilation cavity 14, and then flows out from the multiple first air outlets 16 to clean the filter bags that are close to them. When the steam flows along the vertical frame 9, it will enter the connection hole through the connecting pipe 20, thereby diffusing in the diversion cavity 17, and finally flows out from the second air outlet 18 to clean the filter bags. As needed, the integrated frame 12 between the upper frame 2 and the lower frame 3 is connected through the cooperation of the air supply pipe 15 and the connecting hose 21, so that the steam in the ventilation cavity 14 can flow into the integrated frame 12 and pass through the connecting hose 21. It flows into another integrated frame 12, so that the steam in the upper frame 2 and the lower frame 3 interact to ensure the uniform flow of steam. According to different needs, the connecting hose 21 can also be disassembled and directly connected to multiple air supply pipes 15 through external air supply equipment. Moreover, when using the connecting hose 21, the air supply pipe 15 under the lower frame 3 is in an idle state. According to needs, the air supply pipe 15 can be blocked to allow steam to flow out stably from the first air outlet 16 and the second air outlet 18, or the air supply pipe 15 can be kept unobstructed to allow part of the steam to flow out from the air supply pipe 15 to clean the bottom of the filter bag.
